SCOTTISH TARDIGRADA, COLLECTED BY THE LAKE SURVEY. 661 



hufelandi type, united more than half-way, crescent in front of claws, plain in the 

 young, wrinkled in the adult. Supplementary points two. 



Length 400m (Spitsbergen examples up to 750m). Scotch examples have a 

 papillose process on each leg, not mentioned by Richters. The last leg is sometimes 

 papillose. The crescent is most distinct on the fourth legs, and, except in very large 

 examples, only those are wrinkled. Abnormal additional claws are frequent. 



Orkney (Pomona), August 1906 ; Shetland, Spitsbergen (Bruce), 1906 ; Franz 

 Joseph Land (Bruce), 1897. 



M. harmsworthi, Murray (12). 



Specific characters. — Size moderate, pharynx shortly oval, thickenings 4 in each 

 row, all nearly equal, short, 1| times as long as broad, the first attached to the gullet, 

 an obscure narrow "comma." Claws like those of hufelandi, united about half-way, 

 supplementary points two, a crescent-shaped ridge in front of each pair. Dark eyes. 

 Egg spiny, the spines acuminate, their bases touching, papillose. 



Length, of adult 470m, of pharynx 45m, of young 284m, pharynx of young 30m. 



Shetland. Spitsbergen, Franz Josef Land (Bruce). 



The egg is somewhat like that of M. ambiguus, but is smaller (105m over 

 spines) and has fewer spines. 



M. hufelandi, C. Sch. (20). 



Variety. — The egg figured in Scot. Alp. Tarcl. (8), fig. 6, is very like the type, with 

 the spines shortened till the discoid part seems to lie on the top of a hemisphere. In 

 Shetland many of these eggs were found with well-grown young. The pharynx is 

 sufficiently like the type, but the second (single) rod is nearly equal to the first double 

 rod. The end of the gullet (in the pharynx) is very much thickened. The gullet is 

 narrower than in the type. There is a faint crescent in front of the claws of the last 

 legs. Only one supplementary point seen on each larger claw. No eye seen. 



M. intermedins, Plate (13). (Plate II. figs. 13a, 136.) 

 The characteristic egg, with processes enlarged upwards like little funnels, has been 

 several times found in Loch Morar. 



M. orcadensis, sp. n. (Plate II. figs. 10a to lOe.) 



Specific characters. — Pharynx of the echinogenitus type, having a nut, 3 short rods, 

 and a comma in each row ; teeth curved, with bearers. Claws of hufelandi type, united 

 half-way. Eyes dark. Egg small, spiny, the spines like those of M.furcatus, Murray 

 (9), but the divided points less regularly dichotomous, having 2, 3, or many slight 

 branches ; egg shell between spines dotted. 



Only known from the egg and the newly hatched young. Length of young 230m, 

 pharynx 26m, claws 9m. Fgg 77^- over spines.
